Use location

Connect the piston assembly to the body/One end of the suspension is placed inside the working cylinder, and the other end passes through the oil seal and guide seat.

FunctionTransmits the relative motion between the wheel and the body, driving the piston to generate damping force； Bears both bending loads and surface friction.

Materials and craftsmanshipHigh-strength carbon steel or alloy steel, subjected to high-frequency quenching, hard chromium plating, super-fine grinding, polishing and other processes.

Service lifeThe design life is not less than810,000 kilometers or5Years, the chromium plating layer is corrosion-resistant and wear-resistant.

quality standardskey controls: hardness( HRC 45–55）、 Surface roughness ( Ra≤0.2 m m）、 Coating thickness and roundness.

Customized servicesLength, diameter, surface treatment and end connection form can be customized.
